I think I also want to do no more than a .32 layer with a .4 nozzle (80% of the nozzle)?
Right, I like to be at about 70% of the nozzle size but you can get up to 75% which is 300micron. But that is pushing the limits of a .4 nozzle. The 160micron shells and 320micron infills is a good setup for faster printing. On some objects, infill takes 3-4x as long as the shells, and it is something that you never see when the object is done. So speeding the infill process up helps a lot. If you are wanting to do .3 or .4 shells I would put on a .6mm nozzle. Actually the next step I like is 240micron shells with 480 micron infill, with a .6 nozzle. That gets shit done fast and still looks good. Spritz it with a little acetone afterward and good to go....
